     treatment of certain heart conditions, such as congestive
     heart failure. Chemically it is
  
     (3[beta],5[beta])-3-[(O-2,6-Dideoxy-[beta]-D-ribo-hexopyranosyl-(1[rarr]4)-O-2,6-dideoxy-[beta]-D-ribo-hexopyranosyl-(1[rarr]4)-2,
     6-dideoxy-[beta]-D-ribo-hexopyranosyl)oxy]-14-hydroxy-card-20(22)-enolide.
     The related compounds digitalin and digoxin are also
     extracted from the foxglove (Digitalis lanata and
